We recently got a kitten for our five year old cat, we adopted the new kitten from the rspca .He has had all his shots he has been wormed flea treatment micro chipped, he has been here for over a week. My female cat Esti, has been amazing up till three days ago. She is a very sensitive cat health wise, she is allergic to many things and has breathing issues since she was a kitten . We haven't bought anything new, we haven't put any chemicals down, but we do suspect that she has eaten the kittens food. She has eaten this food before but it made her poop blood so we changed her onto a new one. That was four years ago. But over the past few days she has stopped eating and drinking, won't open her mouth, sleeps behind the couch, and poops and pukes runny see through stuff with blood. The first day of this it was absolutely foul we both nearly threw up. She hasn't peed, I've been syringing water to her the past few day's. But she fights drinking it, she'll just let it dribble out. I'm so scared. I had a cat when I was 15 who died from leukemia with similar symptoms. The difference is that Esti isn't losing weight? I'm so scared and can't help breaking down when she doesn't want anything. Sometimes she will just lay there grabbing my hand 
I'd take her to the vet but we just paid our bills and only have 300 left and I don't know how much it will cost (last vet visit was 700). Am I doing the right thing with the water? I syringe water every hour, we also got cat milk and have been giving her a tiny bit of that each hour. Because it's 40℃ + here at the moment I've put her in an air-conditioned room. Please give me suggestions
